  Opens a new sqlite database at the Path provided.

  `path` can be `":memory"` to keep the sqlite database in memory.

  ## Options

    * `:mode` - controls the flags for sqlite3_open_v2 (see
      https://www.sqlite.org/c3ref/c_open_autoproxy.html). Defaults to
      `[:readwrite, :create]` (opens for reading and writing and creates the

      Single modes are permitted:
      - `:readwrite` - read/write to the database. Does not create the database
        if it is not present. Use in combination with `:create` to create the
        database if it does not exist.
      - `:readonly` - read-only (file must exist).
      - `:create` - creates the database if it does not exist.

      Combinations are permitted:
      - `[:readwrite, :create]` - read/write + create if needed. This is the
        default if not specified.
      - `[:readonly, :nomutex]`
